Unify MachineType and RepType.
...
MachineType now tracks both the representation and the value type of machine quantities and is used uniformly throughout TurboFan.
These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.

Implement representation selection as part of SimplifiedLowering. Representation selection also
...
requires inserting explicit representation change nodes to be inserted in the graph. Such nodes
are pure, but also need to be lowered to machine operators. They need to be scheduled first, to
determine the control input for any branches inside.
This CL requires extensive testing. More tests to follow.
